           Summary: Problems with allocator::rebind::other
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org

 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

The code a.C is rejected by gcc 3.4. This breaks some parts of boost.

Environment:
System: Linux linux 2.4.20-4GB #1 Fri Jul 11 07:33:18 UTC 2003 i686 unknown unknown GNU/Linux
Architecture: i686
SuSE 8.2
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc/configure --enable-threads=posix --enable-languages=c,c++,f77,objc --enable-__cxa_atexit --enable-debug

How-To-Repeat:
source code a.C
template<typename _Tp>
class allocator
{
    template<typename _Tp1>
    struct rebind
    { typedef allocator<_Tp1> other; };

    allocator() throw() { }

    allocator(const allocator&) throw() { }

    template<typename _Tp1>
    allocator(const allocator<_Tp1>&) throw() { }
};

template<typename T>
void f()
{
    typedef allocator<int> alloc1_t;

    typedef typename alloc1_t::template rebind<double> binder_t;
    typedef typename binder_t::other alloc2_t;

    alloc1_t a1;
    alloc2_t a3(a1);
}
